COSMOLOGY

Cosmological Principle Revisited

• actual data: 2dF Galaxy Redshift Survey
  • survey geometry
  • results in 3-D
  • clustering: all galaxies, clusters uncorrected for internal motions
• Implications

Hubble's Law and Cosmic Dynamics

• pattern of Hubble law motions
• interpretations
  • egoist
  • Einstein
